<p>The overall aim of this thesis is to present a fresh perspective on three closely related areas of enquiry: Descriptivist theories of reference, Direct Reference theories and the Carnapian approach to questions of existence and identity. This perspective is developed and tested by a critical analysis of the work of a leading Carnapian theorist, Amie Thomasson, and by looking at some of the central problems associated with our talk of fictional objects. It concludes in an account of negative existence statements and fictional objects as possibly existing objects. In Chapter one I set out the key elements of Carnap’s approach, as that approach was developed over time and in dialogue with his colleague Quine. In Chapter two I explore the relation between the previously mentioned three areas of enquiry through an examination of Amie Thomasson’s brand of Carnapian meta-ontology. In Chapters four and five I develop the view that fictional objects are objects that meet the criteria of existence and identity of at least one linguistic framework but fail to meet the criteria of another, preferred framework. This provides the basis for a neo-Carnapian account of fictional objects in terms of the relations between linguistic frameworks, a novel approach to the questions surrounding such objects. In chapter five, the concluding chapter of the thesis, I further develop my explanation of how there can be truths about fictional and non-existent objects by giving an ontological version of John MacFarlane’s relativity principle. This paves the way for a neo-Carnapian analysis of true negative existence statements. Here I integrate the story I have told about fictional objects and the relations between linguistic frameworks with theories of reference and meaning. In particular, I incorporate a satisfactory concept of the rigid designation of ordinary proper names (and, potentially, of natural and artefactual kind terms). This then leads on to an explanation of how fictional objects, contra Kripke and many others, may reasonably said to be possible objects that, though they don’t exist, might exist under different circumstances.</p>

In this paper, I undertake a novel approach to uncover the forecasting interconnections in the international housing markets. Using a dynamic model averaging framework that allows both the coefficients and the entire forecasting model to dynamically change over time, I uncover the intertwined forecasting relationships in 23 leading international housing markets. The evidence suggests significant forecasting interconnections in these markets. However, no country holds a constant forecasting advantage, including the United States and the United Kingdom, although the U.S. housing market's predictive power has increased over time. Evidence also suggests that allowing the forecasting model to change is more important than allowing the coefficients to change over time.

We present a novel approach to woven-cloth simu-lation in order to generate persistent wrinkles and folds. For a couple of decades, our community has identified and mimicked non-linear buckling of cloth based on the mechanical measure-ment of cloth. It has, however, scarcely paid attention to another important aspect of the measurement, the hysteresis of cloth be-haviors, which is the lag of the amount of forces between stress and relaxation. Our interpretation of the measurement indicates that persistent wrinkles and folds develop in part from the hyste-resis of cloth and its associated energy loss. Thus, we establish an adaptive energy model which takes stiffness coefficients and rest posture values not as constants but as variables over time and behavior. As stiffness coefficients and rest posture values change in proportion to the amount of the energy loss, they appear as persistent wrinkles and folds. Consequently, the clothes simulated by our method bring more realism with respect to visual identi-fication for past behaviors of cloth.

Abstract Historic relationships between communities and waterscapes are complex and often explained solely in technical terms. There is a key need to understand how human-centered developments have shifted the use of river spaces over time, and how these changes reflect on the values of rivers and surrounding cultures. In this paper, we develop a critical analysis of the historically changing relationship between urban communities and water infrastructures using the Georges River catchment in Sydney, Australia. Our focus was on bringing together past and current perspectives, engaging with the formation of diverse hydrosocial behaviors entangled with water infrastructures. Using post-settlement historical documents, maps, journals, and newspaper articles, we trace shifts in hydrosocial perspectives over time, mapping six distinct historic phases. In our study, we offer a shift from the main paradigms currently influencing the development of urban water infrastructures, moving away from the dominant technical propositions of systems designed purely for the management and treatment of stormwater. Drawing on our analysis, we propose a new urban water design concept: Culturally Inclusive Water Urban Design (CIWUD). This presents an advancement on current framework to include a consideration of people's connections and uses of urban waterscapes, as well as a shift towards democratic space design.

Semantic realism fits Millikan's account of kind terms in its focus on information-theoretic abilities and strategic ways of gathering information in human communication. Instead of the traditional logical necessity, we should interpret rigid designation in a dynamic semantics as a legislative act to constrain possible ways in which our belief may change.

Many research techniques are well-accepted within the Information Systems (IS) discipline.  From time to time, however, a researcher investigates a question that requires a novel approach.  It is then incumbent on the researcher to justify that approach. The IS discipline has accumulated a large corpus of published works.  A project is being undertaken whose purpose is to establish the conceptual foundations for a research technique for the critical analysis of published works, and to develop methodological guidance for its application. This article discusses the challenges that have confronted that undertaking.

The identification of deterioration mechanisms and their monitoring over time is an essential phase for conservation. This work aimed at developing a novel approach for deterioration mapping and monitoring based on 360° images, which allows for simple and rapid data collection. The opportunity to capture the whole scene around a 360° camera reduces the number of images needed in a condition mapping project, resulting in a powerful solution to document small and narrow spaces. The paper will describe the implemented workflow for deterioration mapping based on 360° images, which highlights pathologies on surfaces and quantitatively measures their extension. Such a result will be available as standard outputs as well as an innovative virtual environment for immersive visualization. The case of multi-temporal data acquisition will be considered and discussed as well. Multiple 360° images acquired at different epochs from slightly different points are co-registered to obtain pixel-to-pixel correspondence, providing a solution to quantify and track deterioration effects.

Abstract Combining a stylistic approach with chemical analyses and focusing not only on composition but also on production technology, this research aims to identify possible centres of post-medieval production of glass as well as decorative production techniques used in stained glass, in particular the grisaille. The use of several combined analytical techniques allowed for the unveiling of the composition of glass and the structure of grisailles. Sorting out the grisaille structure sheds light on the processes employed to produce paints, while compositions of glass objects are used to propose production provenances. Both contribute to the study and critical analysis of how glass heritage has developed over time, including materials and technical practices, uncovering the transfer of technology and movement of people and goods.

Dive Profile

In scientific and technical diving, the survey of unknown or partially unexplored areas is a common task that requires an accurate planning for ensuring the optimal use of resources and the divers’ safety. In particular, in any kind of diving activity, it is essential to foresee the “dive profile” that represents the diver’s exposure to pressure over time, ensuring that the dive plan complies with the specific safety rules that have to be applied in accordance with the diver’s qualification and the environmental conditions. This paper presents a novel approach to dive planning based on an original underwater pathfinding algorithm that computes the best 3D path to follow during the dive in order to be able to maximise the number of points of interest (POIs) visited, while taking into account the safety limitations. The proposed approach, for the first time, considers the morphology of the 3D space in which the dive takes place to compute the best path, taking into account the decompression limits and avoiding the obstacles through the analysis of a 3D map of the site. Moreover, three different cost functions are proposed and evaluated to identify the one that could suit the divers’ needs better.

Bacteriophages are viruses capable of recognizing with high specificity, propagating inside of, and destroying their bacterial hosts. The phage lytic life cycle makes phages attractive as tools to selectively kill pathogenic bacteria with minimal impact on the surrounding microbiome. To effectively harness the potential of phages in therapy, it is critical to understand the phage–host dynamics and how these interactions can change in complex populations. Our model examined the interactions between the plant pathogen Erwinia amylovora, the antagonistic epiphyte Pantoea agglomerans, and the bacteriophages that infect and kill both species. P. agglomerans strains are used as a phage carrier; their role is to deliver and propagate the bacteriophages on the plant surface prior to the arrival of the pathogen. Using liquid cultures, the populations of the pathogen, carrier, and phages were tracked over time with quantitative real-time PCR. The jumbo Myoviridae phage ϕEa35-70 synergized with both the Myoviridae ϕEa21-4 and Podoviridae ϕEa46-1-A1 and was most effective in combination at reducing E. amylovora growth over 24 h. Phage ϕEa35-70, however, also reduced the growth of P. agglomerans. Phage cocktails of ϕEa21-4, ϕEa46-1-A1, and ϕEa35-70 at multiplicities of infections (MOIs) of 10, 1, and 0.01, respectively, no longer inhibited growth of P. agglomerans. When this cocktail was grown with P. agglomerans for 8 h prior to pathogen introduction, pathogen growth was reduced by over four log units over 24 h. These findings present a novel approach to study complex phage–host dynamics that can be exploited to create more effective phage-based therapies.
